I've an application under tomcat.
When only a one or two users works on it everithing is ok.
When the number of users grows the application slows down.
Is not a memory nor a cpu problem : using top I see the system resources quite

the Servlet output stream (more or less 300kb).
In 7 it works perfectly (100ms).
In 8 , depending from the network connection and mainly from the
